This invention relates to machines for inmechanisms by contact with the Work and causserting such fastenings as nails, and is particu ing engagement between :ie thus-located mechalarly concerned with apparatus of the character nism and an adjacent mechanism to position the of that disclosed in a patent issued in my name latter. This locating effect of one mechanism on November 24, 1925, and numbered 1,562,516. upon another may be continued throughout a This apparatus is especially adapted for nailing series.

Thus,

To accomplish this, I member against said work. Similarly, a single arrange each fastening-inserting mechanism to connection, as to the Work-contact member, may

move relatively to support carrying the work, be utilized to separate the mechanisms normally about an axis individual to such mechanism, the from the support, and thus allow the work to be axes about which the various mechanisms move brought to operating position thereon Without being substantially parallel. The work-support danger of its being marred by rubbing contact 40 or jack is preferably movable, traveling verwith the mechanisms. As illustrated, this con- 9 tically toward and from a generally horizontal nection acted upon by the movable Work-supabutment or die-block, with which it co cperates, it being made to a vertically movablejackand the axes'of oscillation of the mechanisms carrying cross-head.

This allows the member to fasten accurately in the or other travel with the support at such times as when ore-portion, regardless of lack symmetry of clamping pressure is being applied to the Work adjacent gaging surfaces. 1 accomplish this by in preparation for driving the fastenings.

positioning one of plural fasteni g-inserting Another object or my invention is to prevent 119 displacement of the fastening-inserting mechanisms during the driving operation, and this 1 effect by associating with the mechanisms a positive locking member acting in the movement of the member which actuates the inserting mechanisms. Herein is disclosed such a member in the form of a wedge movable between one of the inserting mechanisms and a relatively fixed member, preferably a portion of the die-block, said member and inserting mechanism having contacting surfaces intersecting the direction. of movement of the mechanism.

In nailing the heel-portions of shoes, as the heel-seats, a comparatively small change in the angle of the work about a vertical axis from the proper position will seriously affect the metrical relation of the nails to the crease of. the shoe. As a further object of the invention, there is furnished means whereby the operator may readily and accurately locate a shoe for the operation upon it, and without the necessity for giving it special consideration. For this pur pose, I. associate with the shoe-support and nailing mechanisms a gage member having a portion arranged to contact with opposite sides or" a shoe on the support, the opposite contact-surfaces of the gage diverging outwardly in the direction of the support. This member may be so located that it engages a shoe adjacent to the breastline, near points where the opposite sides of both right left shoes are equidistant from the longitudinal axis of the shoe-bottom. When the support presents a shoe for nailing, if this is displaced angularly or laterally, it will, upon entering he throat between the contact-surfaces. be caused by the action of the surfaces to be moved until it is correctly disposed with respect to the nailing mechan'sni. To avoid interference of the gage with the movement of the support, it is preferably yieldable in the direction of such movement.

As still another object of the invention, I provide for the maintenance of a symmetrical disposition of the nailing at opposite sides of the heel-portion of a shoe when this shifts laterally under pressure preparatory to the insertion of the nails. This movement may be caused, for example, by irregularities in the cone of the last. To prevent this lateral displacement, the shoesupporting jack has a top connected to it by a universal joint. The contact-surfaces of the joint are curved about a point lying, during the nailing operation, substantially in the pressuresurface of the abutment or die-block, against which the jack forces the work. Consequently, as the jack-top swings to accommodate itself to the work, said top may rock so opposite sides will rise and fall, but the of the heel-portion remains coincident with this axis at the dieblock, and t -ere is no displacement of the points of insertion of the nails in the heel-portion.

A single embodiment of my invention appears in the accompanying drawings. Here, 7

The general characteristics of the machine which I have chosen to disclose herein may be substantially those of the apparatus of Patent No. 446,885, Pope, February 24, 1891. This includes a frame 10 having separated portions, between which extcnds a horizontal die-block 12 furnishing an abutment, against the under side of which is pressed the heel-seat of a shoe S to be nailed. At the area of contact of the heelseat with the die-block is shown a recess 14 formed at the under side of the block, this recess serving as a mold which, as a result of the pressure applied during the nailing operation, imparts to the heel-seat the contour of the concave end of the heel which is to be later attached. The shoe S is carried upon a jack-post 16 mounted to movein ways 17 extending from front to rear of the frame, the ways being at the top of a cross-head 18 arranged to reciprocate vertically in the frame. With the cross-head in its lowered position and the jack drawn out, the shoe to be operated upon may be placed upon said jack and then pushed along the ways 17 until the heel-portion is beneath the recess 14. In this position, the machine may be operated to apply pressure to the heel-seat to form it and hold it for the insertion of the nails. When there is no last-pin on the post 16, as is herein disclosed, said post may be clamped in place on the cross-head beneath the die-block, and the shoe introduced above it into operating position.

The die-block is preferably formed in horizontal sections, joined by bolts 22. At the rear of the block are shown three passages 24 contained in bushings 26 extending "hrough the die-block (Fig. 3). These passages are situated above the rear of the heel-seat and are inclined downwardly and inwardly. At the upper extremity of each passage 24 is a downwardly converging throat to receive a driver 28 fixed on the lower portion of a head 30 secured at the center of a top girt or yoke 27 carried by vertical side rods 29, 29 movable in the frame at the ends or" the die-block. This top girt and head are reciprocated by the side rods under the power of the machine after the cross-head 18 has been raised to place the work under pressure. Above the recess 14, and extending at each side thereof between the block.- sections, is a space in which are mounted for independent horizontal movement nail-inserting mechanisms, each possessing a body-section 32 and a supporting portion or arm 34 projecting outwardly and rearwardly therefrom at a somewhat obtuse angle. The arms are arranged to oscillate about vertical spindles 36 extending between the upper and lower block-sections. An adjustment may be provided for each of these axes of oscillation, the purpose of which will later appear. A portion 33 of the spindle, about which each arm. 3 turns, is eccentric with respect tothe spindle-ends which are in the dieof the eccentric may be varied by turning the spindle and fixing it in position by a clamping nut 40 threaded upon its upper extremity.

In each body-portion 32 is a nail-receiving passage 42 terminating at its lower end in a nozzle 44, in which the nails N are held in preparation for driving. These nozzles move with the sections in proximity to elongated openings 45 in the under side of the die-block, the openings extending in two series along the opposite sides of the recess 14. Each passage 42 is preferably inclined downwardly and inwardly, so that the fastenings in the nozzles will be driven toward the interior oi the shoe, and not along or in the direction of the counterportion. By this arrangement, the heel-seat-securing fastenings may be inserted close to the edge of the outsole, to produce a tight rand-crease, without danger of their emerging through the upper. The same effect is produced by the inclination of the fixed passages 24. Nails are delivered directly to the rear passages, and to the passages 42 through communicating passages 46 extending up from the driving passages, by loader mechanism 48 arranged to turn about one of the side rods 29. Mounted to move in each passage 42 is a driver 50 secured in the lower extremity of a plunger 52 reciprocable in the corresponding section and held normally above the lower extremity of the nail-delivering passage 46 by a spring 54 surrounding it. To drive the nails through the nozzles into the heel-seat of a jacked shoe, the drivers 50 are simultaneously depressed by contact of the under side of the head 30 with the upper ends of the plungers 52. The drivers 28 at the same time insert the nails in the passages 24.

It is desired that all the two side series of nails inserted by the sections 32 shall be placed in the outsole close to the rand crease and substantially uniformly spaced therefrom for all sizes of shoes. For the rear nails inserted by the drivers 28 the location changes little with difierent sizes, the work being gaged from this extremity by con tact with a back-stop 55 adjustably mounted upon the rear of the frame at the back of the dieblock. The relation of the sections of each of the side series as a whole I determine by engagement of one of the sections with the counterportion of the shoe operated upon, and the con panion sections of the series by engagement with the thus-located section and with one another. I have chosen the rear section of each series for engagement with the work, since this part of the counter-portion of a shoe-upper is invariably substantially symmetrical at its opposite sides. As the upper curves forward from the rear, one side of the counter-portion may project more over the crease than the other, so that, ii' the gaging be by direct contact with the work throughout the series or nailing sections, the symmetry of the points of insertion with respect to the crease would be destroyed. Depending from the under of each rear nailing section '32 is projection 56 (Fig. 7), extending below the die-block. Adjustable laterallyof the projection. by virtue of a slot 58 and a clamping screw 60 threaded into the end of the projection, is a block 62 carrying at the upper side of its inner end a contactroll 64. The periphery of the roll is preferably inclined downwardly toward its axis to more closely conform to the inclination of the surface of the shoe-upper which it is to engage. The roll turns about a spindle'66 rising from the block 62, and, since the jacked work rises for the application of pressure after the roll and shoe-upper are in contact, said roll is allowed to move longitudinally of its spindle. There is, consequently, no rubbing of the worksurface over the roll, doing away with the liability of marring the former. Moreover, the roll is caused to remain close to the crease, where the outward curvature of the upper is approximately the same at both sides. This avoids displacing the work laterally, because of considerable variations in form which may occur farther frointhe crease. At the forward side of the block 62 is a rounded contact-projection or boss .68, which is engaged by an inclined cam-surface upon a plate '72 secured to a downward projection .56 from the next section and in a manner similar to that of the rearsection, except it may be made non-adjustable. At the opposite end of the plate 72 from the cam-surface '70 is a cam-surface 74, which, in turn, engages a rounded projection '16 formed upon the adjacent extremity of a plate 78 secured upon the succeeding section. A camsurface 8-1) upon the outer side of the plate 78 acts upon a roll 82 surrounding a depending projection of the last or forward section of the series. All the projections are respectively individual in their sections and their cam-surfaces are shown as inclined outwardly and rearwardly from the breast-line of a shoe on the jack-post. Engagement of the roll 64 of either series of nailing sections with the counter-portion of a jacked :shoe and of the various contact means of this and the succeeding sections with one another is yieldably eiTected by a spring 84 (Fig. 5) situated in a bore in the forward portion of one side of the die-bloclnthis spring being seated at one end against a screw '86, and at the other extremity forcing a plunger 88 against the depending portion of the corresponding forward nailing section. To produce normal separation of the sections to give a space into which the jacked shoe may be moved, without engagement with any part of said sections, the rear section of each series is joined by some such connection as a flexible member 90 to the cross-head 18 carrying the jackpost.

When the cross-headis depressed, before the ma chine is put in operation, the pull upon the'membars 90 draws out the rear section of each series, and this movement is communicated by the cooperating contact means through both series of sections, carrying them all to their inactive positions against'the expansive force of the springs 84. After the work has been placed upon the jack-post between the sections 32 and the machine started in operation, the elevation of the cross-head with the post and work relaxes the pull upon the members 9i), allowing the springs 84 to force all the sections in until the rolls 64 engage the counter-portion of the shoe, and the companion sections are correspondingly located by their cam-surfaces and co-operating projections. Included-in each of the flexible members 90 is a spring 92, the elongation of which compensates for any diflference in the amount of travel between the cross-head and the rear sections.

The axes of the spindles 36, about which the ference with the closely spaced adjacent seotions. When thus arranged, as may be seen from cross-head the shoe is, if displaced a consideration of Fig. 6 of the drawings, the respective points of insertion a and b of the nails may be spaced for the proper proportionate distance from both the rand-crease-lines c and from the breast-lines d of the largest shoe S and the smallest shoe 3 and for the intermediate sizes. By oscillating the sections about individual vertical parallel to the direction of movement of the work into and out of nailing position, closely placed scc"ons may be located side by side without interior ence with one another, so a suitable number of nails to obtain secure attachment may employed. The cams upon the section-plates 72 and 78 are so designed that, the correct location of the rear section 32 having been attained by the engagement of its roll 64 with the shoe-upper, the remaining sections of each series wil be positioned by contact with this section and with one another, they thus being rendered independent of the form of the counter-portion at opposite sides, b th as to ver tical and horizontal contour. Adjustment of the. rolls 54 by the connections at 58 governs their normal relation to the cam-surfacelo, and

- therefore the location of the entire series with respect to tr e spacing of the nailing points toward and from the crease and breast-line, the forward sections being controlled in this respect from the section. A further individual adjustr out as to this spacing is obtainable by a variation in the axes of oscillation of the sections through the eccentrics 38. It should be noted that for any particular nailing design, such adjustments are unnecessary, and that the contact means, furnished by the roll 64 and the succeeding surfaces 68, 10, 7e, '15, 80 and 82 which con rol the positions of the sections, might all be formed as integral portions of said sections.

An angular displacement of the work will causethe points of insertion of the nails to approach one side of thcheel-seat retreat from the apposite side affect the, desired relation to the rand- To enable the operator to gage the work ut effort, there is mounted near the front of the die-- lock 12 a member 98 having a stem 98 movable along a vertical bore, but held against turning therein. A spring 100 interposed between the spindle and the upper extremity of the bore holds the member normally in its lowest posifon, at which it is adapted for engagement with the smallest size of shoe to be nailed, as well as largest. The member 96 is in the form of an inverted yoke, having at its ends, in symmetrical relation to the opposite series of nailing sections, upwardly and inwardly conver ing surfaces 102, 192-. These surfaces are so placed that the'heel-end of a jacked shoe enters between contacts with them at points adjacent to the breast-line and approximately or idistantfrom the longitudinal axis of the shoe. may readily be found and are the The length These points same for both right and left shoes.

and inclination. of the gaging surfaces 192 are b er. against the back-stop lifted tow rdsthe recess 14 by the elevation of the laterally y, shifted upon the post until its or gangulai having a socket 112 in the longitudinal axis is correctly alined. As the upward movement continues, the member 96 yields against the spring 109, so that the proper molding contact with the recess 14 is insured for all shoe-sizes.

The shoe upon the jack-post 16 having been elevated by the cross-head 18 so the heel-seat is forced into the die-block-recess, the nailing sections are relieved from the pull of the members 90 and allowed to move into nailing position under the influence of the spings 84. Outward displacement of the sections through the forces applied in driving the nails must be prevented. This I accomplish positively by the following means: Arranged to slide vertically at each side, near the forward edge of the head 30, is a wedge member 104. Each wedge is yieldable against a'sp'ring 1G6 situated in a recess in the member and abutting at its upper end against the top of the bore in which the member moves. As the head descends, the tapered extremity of each of the wedges passes between the outer side of the corresponding forward section 32 and some such relatively fixed surface as the vertical Wall of the recess n the die-block in which the sections move. The angle of inclination is such that the force exerted by the sections against the wedge cannot displace it, so the entire series is effectively locked for the insertion of the nails by the drivers. Dilferent positions of the forward sections for different sizes of. shoes operated upon are provided for without impairing the positive locking effect by the yield of the springs 106, allowing the wedges to remain at rest while downward travel or" the head continues.

When pressure is applied to the work through the rise of the jack-post 16, it is desirable that the surface of the post which contacts with the cone of a last L, upon which a shoe is presented to Le machine, shall be able to accommodate itself to varying inclinations of contact-surface of the cone. For this purpose, the post has, mounted upon its upper extremity, a top 108 provided with an upper contact-surface 110. The top is universally movable upon the post by a joint post to receive a partly spherical portion 114 on the under side of the top. A tension-spring 116, uniting the post and top, allows the latter to tilt in alldirections from its normal position, in which the surface 110 is horisontal, and thus furnish perfect engagement with the contact-surfaces of all last-cones. Unless the universal connection were properly organized, lateral movement of the work, caused by the shifting of the top, might throw the points of insertionof the nails to one side or the other and thus interfere with the desired relation to the rand-crease. To prevent such an efiect, I

curve the contacting surfaces of the socket 112 and ball 11. upon arcs, the common center of which is substantially in the contact-surface of the recess 14 and at the longitudinal axis separating the series of nailing sections. Consequently, whie the points of insertion may rise and fall somewhat, as the jack-top moves, their lateral relation remains practically unchanged, and the symmetry of the nailing is unaffected.

In using the mach e illustr ;ed as embodying this invention for na... ng the heel-seats of shoes,

lasted upper S is placed with last-cone the top 108 of the jack and located with respect to the nail-inserting means by the backstop 55. At this time, the movable nailing sections 32 are held in their outward positions, re-

moved from the jack, by the tensioned connections 90 to the cross-head 18. These connections act directly upon the rear movable sections, the eiIect being communicated through the series at each side of the jack by their successive contact with one another. When the machine is started and the cross-head and jack rise, the upper is trued laterally by t 1e gaging surfaces 102, and is clamped against the molding recess 14 in the die-block. The pull of the connections 90 relaxed, and the rear movable nailing sections freed so the springs 84 are allowed to force all the sections to a relation with the heel seat determined by the engagement of the rolls 6% with the counter-portion of the upper, the contact of the successive sections with or e another. Following this, the wedges 10s positively lock the movable nailing sections by their insertion between the forward sections and a fixed wall, and the nails N, which have previously been delivered to the passages 42 in the sections and to the fixed passages 24 by the loader 48, are driven into the heel-seat by engagement of the descending head 30 with the plungers 54 of the drivers in the sections and by the drivers 28 fixed in said head. Upon the elevation of the head 30 and the lowering of the cross-head 18, the various elements are restored to their normal positions.
